Esmerelda points out that this is an old story - from 2016. Nevertheless, it's instructive. Jews News reports:

A HUGE stash of AK-47 weapons reportedly belonging to Islamist extremists have been found hidden near a mosque in Germany.

The weapons arsenal was discovered during a top secret raid by a SWAT team in Nordrhein-Westfalen. Local politician Ismail Tipi revealed details of the raid and warned of “the danger of fundamentalists”. The weapons were found in a cold room of a greengrocer near a mosque. Its the most populous state in Germany with nearly 18million people in the area, which includes Dusseldorf.

Mr Tipi, who is a member of the Hessian parliament, warned of the dangers of Salafi fundamentalists. He Says that The danger of fundamentalist Islamists who are ready to use violence arming themselves in Germany is very large. This secret raid finding this weapons cache makes this more than clear.

(...)

Mr Tipi, who is said to have received death threats for his comments against jihadis, raised concerns sleeper cells are gearing up for a terror attack on Germany.

He said: “The information about this is increasing. The fear is large that Salafist sleeper cells, jihadis, and ISIS terrorists in Germany get support from foreign intelligence services that are not friendly to us.

“Through the weapons arsenal, the sleeper cells and militant jihadis can be armed with weapons and prepare for their likely attack. This is exactly what I have always feared.”

The photo of a stack of weapons is actually from the USN seizure from a dhow in the Arabian Sea in March 2016. See: ttps://news.usni.org/2016/04/04/u-s-navy-seizes-suspected-iranian-arms-shipment-bound-for-yemen
